7 Claims.

This invention relates to a device which is ef fective for properlylubricating axles and simultaneously preventing waste grabs which causehot'boxes particularly on railroad car axles.

In railroading terminology waste grabs occur when rotating journalsoperating in journal boxes carry small portions or chunks of cottonwaste or lubricating packing upwardly to the bearing, usually brassbearings, which lodge between the bearing and the journal. When thechunks of packing are thus lodged, friction of the rotating journal willgenerate heat and ultimately the heat will ignite the packing in thejournal box. Unless the burning packing is discovered, a hot box willresult and generally the bearing is destroyed and the journal will bedamaged. Hot boxes are very expensive in that destroyed bearings greatlydamage the journal and in some cases have caused wrecks.

Previously different devices have been designed to lubricate axles onrailroad cars. Also, different devices have been designed to preventwaste grabs. Generally, however, the different devices were not designedto accomplish the dual function of properly lubricating car axles and atthe same time prevent waste grabs.

The main object of this invention is to provide a simple and practicaldevice which will properly lubricate bearings and axles, and at the sametime substantially eliminate waste grabs in journal boxes on railroadcars and other moving means of transportation involving similarstructure.

Another object of this invention is to provide a device by means ofwhich large amounts of lubricating packing can be saved, thus greatlyreducing the cost of packing and lubricating journal boxes.

A further object of this invention is to provide a device which isclamped between the top of the bearing and the wedge or other partsupporting the bearing in position thus permittinglongitudinal andtransverse movements with the normal movements of the bearings,(ofttimes referred to as brass in railroad terminology) and assuringprotection at all times to the bearing against waste grabs.

An additional object of this invention is to provide a device throughwhich the lubricating material, as cotton waste, is held in suchpositionthat optimum lubricating value will be obtained between thebearing and the journal.

These and other objects, features and advantages of my waste grabpreventer and lubricating device will appear from the followingdescription, wherein reference is made to the accompanying sheet ofdrawings.

In the drawings,

Figure 1 is a perspective view of the waste grab preventer andlubricating device.

Figure 2 is a vertical section through a conventional journal boxarrangement in a plane parallel to the journal axis, the journal beingin elevation and the device illustrated in Figure 1 in section.

Figure 3 is a section taken in the plane of line 3-3 in Figure 2illustrating the position of the waste grab preventer with reference tothe journal, journal bearing and the packing.

Figure 4 is a fragmentary vertical section through a journal box in aplane parallel to the journal axis, showing the waste grab preventer inelevation with reference to conventional parts in a journal boxarrangement, and

Figure 5 is a plan View of the waste grab preventer in elevation andpositioned over the journal bearing and other conventional parts in ajournal box.

Similar reference numerals refer to similar parts throughout the severalfigures and description.

In the drawing, I0 denotes a conventional journal box with a hingedcover I2 and an axle 14 extending into the box M. The journal [6 on axlel4 being of conventional design has a fillet l8 and collar or end flange26. A conventional journal bearing 22 is positioned on journal [6, andthe bearing 22 is held in position by means of the usual wedge 24. Asuitable dust guard 26, is provided in the journal box. The bearing 22is provided with cars 28.

The waste grab preventer and lubricating device 30 in its simple form asshown in the drawings, especially Figures 1, 2, and 3, comprises aframe, preferably sheet metal, with asubstantially fiat top 32, which isshaped to conform to the upper surface of bearing 22. The top 32 isgradually sloped downwardly and finally merges into parallel side walls34, the lower portions of which are at substantial right angles to thetop 32. The side walls 34 extend downwardly on each side of journal [6to points about in line with or below the center line of the journal.Projected portions 36 which correspond to the shape of ears 28 of thebearing 22 are provided adjacent to the flat top 32.

Fastened to the lower or bottom edges of the side walls 34 is aforaminous material 38 which forms a loop between the side walls 34. Theforaminous material is preferably fastened to the lower edges bycrimping as shown at 39, although any means of fastening may be used.The ends of the foraminous material 40 and 42 extend beyond the ends ofthe frame side por tions as shown in Figure 1. In practice the end dBshould extend about 2 to 4 inches beyond the frame, and end 42 shouldextend about 1 to 2 inches beyond the frame side portion. These extendedend portions, viz. 4B and 42, serve a very useful purpose as illustratedin Fig, 2 and will be described more fully below. The foraminousmaterial is preferably heavy canvas as for example about 10 ounce weightmaterial, al-. through any weight canvas, webbing, o'r other foraminousmaterial which will withstand hard wear may be used with satisfaction.

The waste grab preventer and lubricating de-, vice is positioned betweenthe top of the bearing 22 and the wedge 24, and the looped forami-noiismaterial 38 is passed below the journal It. A suitable quantity of oilsoaked lubricating packing 44, as for example, wool waste, cotton waste,etc., is then inserted into the journal box between the foraminousmaterial 33 and the bottom of the journal box. As the lubricatingpacking material is inserted, the foraminous material is pushed upwardlyin loose folds 45 against the lower; portion of journal 85 asillustrated in Figuresz and 3. Ihe extended end 48 of the foraminousmaterial is then folded downwardly and positioned or tucked between thepacking id and the bottom of the journal box as shown at 38. Theextendedend d8 will fold itself into position against the fillet l8 andthe dust guard 25 as s we at It is evident that since the foraminousmaterial hold s the packing'in a confined area, no material can normallybecome lodged between the journal and the bearing. The oil contained inthe packing material will soak through the foraminous material and thuslubricate the journal. The amount of packing material required toproperly pack the journal box will be considerably less than isgenerally placed in journal boxesheretofore. Since the frame has ears 36which clamp over ears 28 of the bearing as shown in Figure 5, the wastegrab preventer will follow the lateral or any other movements whichabearing makes when the car is travelling.

Having described and illustrated my invention in one of its embodiments,I claim as follows:
